Specification of Letters Patent.

Patented Apr. t3, 1915.

Application filed February 8, 1913. Serial No. 7,116,995.

Bc it known that we, JOSEPH SACI-1s and (f nAuLns A. FuANcrs. citizensot the United States. residing at Hartford, in the county ol' Hartfordand State of Connecticut, have invented certain new and usefulImprovements in Attaclunents for Incandescent- Lamp Sockets, ol whichthe lollowlng is a specification.

fihis invention relates to attachments for incandescen-tdamp socket-samong the principal objects of the invention being the provision of anarticle of this character which is simple in construction and which canbe quickly applied to and as readily removed from a socket but whichwhen in position thereon will be hold against accidental dislodg-ment ina positive and certain manner. i The invention possesses other featuresof novelty and advantage which with the foregoing will be stated atlength in the following description wherein we will set forth -in detailthat form of embodiment ot the invention which we have selected forillustration `in the drawings accompanying and forming part of thepresent specification. to

enable those skilled in the art to practise the invent-ion. W e candepart from this showing in several particulars -Within the scope of theinvention delined by the claims fol Alowing said description.

Referring to said drawings: Figure l is a front elevati-on of anattachment involving our invention. Figs 2 `and 3 are respectivel)y aside elevation and top plan view of the same. and, Fig. 4 is atransverse see tion on'tlxe line fl--il ot' Fig. 3. showing the socketomitted from the other figures.

Like characters refer to like throughout the several views.

Our invention can be incorporated in parts \\idel vdiii'erent kinds ofdevices being represented as embodied in a reflector in which connectionit is of particular utility: it can bo employed with equal advantage inman v other cmmections, for example in a guard for incandescent lamps.

'lhe bodlr of the device illustrated con! f sists of a Areflector member2. being approxi mately ol semi-obovate 0r half pear form, although thisparticular shape 1s not always Anecessary. and -generally but notnecessarily,

consists of a sheet-metal shell. In the main` 'the clip and after whichsaid clip said body is like that found in the so-called half reflector.

Extending outward from the reflector member or body portion. 2 is a neck3 and although the two parts are preferably integral vthis is not alwaysnecessary. The neck as shown presents a cla-mp or clip boing adapted tovieldingly embrace the socket el. of an incandescent lamp and while thisyielding relation can be obtained in several ways, the best results aresecured by makin-g said neck or clip resilient. As 'shown the said neckor clip is of substantially circular form being preferably lout notessentially a little more than half a circle but less than a full circlein extent. The interior diameter of the said clip is slightly less thanthe external diameter of the socket so that the clip will tightly hugsaid socket. Owing t0 the construction of the said neck or clip in themanner described, there is formed therein the lateral mouth or slot 5from .which it will be clear that said clip is applied to and removedfromlthe. socket by a relative lateral motion. While there may he caseswhere the grip of the clip upon the socket due merely to frictionsupplemented by the resilience of said neck is sufficient to hold theattachment in place we prefer in all cases not to rely upon this but toprovide in addition thereto, a positive holding means which willposition the attaclnncnt in definiti` relation lonL g'itudinalli,1 ofthe attachmentwand such means may vary radically. For this purpose wehave 'furnished an in terlock between the two parts; coi'isisting forigv'ample 'of a channel in one to receive a bead on the other, thesocket Ll as illustrated having such a bead as G and the neck P, havingan internal channel or groove as 7 to receive said bead.

In applying the article the neck 3 is placed against the socket 4t withthe latter partly in the mouth 5 and the parts are rela tively laterallymoved toward each other which has the. effect of opening the neck orclip 3 to its maximum extent at which point the socket will bepractically wholly within Will snap instantly in place, the groovereceiving the bead 6.

It should be observed that the neck or clip B abruptly joins the reectogbOdy 2 j 15 outer edge, Withfabead 9, and thishead may i 20 cecds the,length "of the -lamporfof theexf;A
